1 Claim.

This invention relates to a novel construction of hose reel, and moreparticularly to a hose reel which is supported upon an industrial truck;hoses leading toopposite ends of an operating cylinder which may bemounted upon and movable with the main carriage of said truck and whichcarriage is raised and lowered along the Vertical mast with which suchtruck is provided.

Among the general objects of the invention are to provide a hose reel ofthis type with particularly elcient means for supplying operating fluid,through the central support upon which it is rotatably mounted, to thehoses on said reel; also to provide the said reel with means whereby itmay be conveniently mounted upon and incorporated with the front portionof an industrial truck.

Further and more limited objects of the invention will appear inconnection with the description and drawings hereof and will be realizedby the combinations Iof elements covered by the respective claimsappended hereto.

Referring to the drawings. Fig. l represents a somewhat diagrammaticside elevational view of an industrial truck of the type with which myinvention may be advantageously employed and illustrating the manner inwhich the reel is mounted upon the said truck and also the manner inwhich the delivery ends of the hoses are connected with an operatingcylinder mounted upon the carriage of said truck which is verticallymovable along the mast thereof; Fig. 2 is a vertical sectional viewthrough the reel, corresponding substantially to the line 2-2 of Fig. 3and looking in the direction of the arrows, and showing the parts bywhich it is supported on the truck; Fig. 3 is a sectional viewcorresponding to the line 3--3 of Fig. 2 and looking in the direction ofthe arrows; Fig. 4 is a detail in section of what diagrammatically, thebody of an industrial truck of a well known type, the same beingprovided with side frame members comprising upturned iront portions I I,I2 denotes one of the 1oz-ver side members of a mast the lower portionVof which is supported for pivotal movement about a horizontal axis, `ina well-linown manner. I3

denotes the hood. the same being provided with a iioor supported by thebottom portions of the upturned portions II of the side frame members.

I4EL denotes one of the sides of a main supporting carriage I4 mountedupon and vertically movable along the lower side members I2 of the mastand along the side members I2a of its extension, th-e carriage beingraised and lowered, preferably by means of a cylinder and plungerinterposed between the lower side members I2 of the mast and having across head, the opposite ends of which support rollers, with chainssecured each at one end to a non-movable portion of the truck and attheir opposite ends to the carriage t4. This construction, as well asthe means for pivotally supporting the lower end of the mast I2 are oldand well known in this art and are shown, for instance, in the patent toWeaver No. 2,299,445, issued October 20, 1942.

I5 denotes a platform which is rotatably mounted upon an arbor carriedby the main or supporting carriage I4 and is provided with lifting forksI6; also with a supporting member I'I` secured to one' side thereof, thesame being in the general form of a scoop and which is adapted to engageone end of an object, such as a paper roll IB, thereby to support thelatter 'when the carriage I5 is rotated about its supporting axis. Themanner in which the platform I5 is rotatably supported upon the carriageI4 does not constitute, in its details, any part of the inventionintended to be protected herein, and it may be of the type shown in thepatent to Lehmann et al. No. 2,281,004, issued April 28, 1942.

I9 denotes a cylinder which is supported by the main carriage I4, thepiston rod 2D whereof is connected to the 'rotatable carriage I5, as bya pin 2I and a plate 22 secured to the rear of the latter carriage.

For the purpose of supplying operating uid to opposite ends of thecylinder, I have provided the front of the truck proper with a reel bywhich hoses for supplying such fluid to opposite ends of said cylinderare supported. 23 denotes one of the side walls of the hood I3 which issecured at its lower end to the member II (see Fig. 2). 24 denotes thebottom, 24n the top and 24b the side of a cylindrical reel casing whichis fastened at its upper end to the wall 23 as by means of rivets 25extending through the said wall, through an extension 24c of the bottomwall 24, through an4 upper clamping member 26 land through a washer 26B.The lower portion ofthe wall 24 is secured to one of the side membersII, as by means of bolts 2l.

28 denotes a dual-ported fixed spindle the lower end of which isanchored to and within va central collar 29 provided therefor on andsecured to the bottom plate 24. This spindle is cylindrical in contourand is provided with grooves 30, 3I and 32 extending therearound for thereception of piston-type sealing rings 33. Between the grooves 30 and 3Ia wide annular channel 34 is provided and a similar channel 35 isprovided between the grooves 3| and 32.

, 36 denotes a hub which is mounted for rotation upon the body portionof the spindle 28 and which provides annular passages with the channels34 and 35, to form a swivel fluid joint.

Extending around the top and bottom of the hub are angular seats 31 and38 upon which seats there are secured the inner cylindrical edges 39aand 41|a of upper and lower annular plates 39 and 4U of the reel. Anannular plate 4I the periphery whereof is of the same extent as theperipheries of the plates 39 and 40 is located intermediately betweenthe former plates and is welded at its inner edge to a wall 42 whichextends between and which is welded to the plates 39 and 40. vThe Wall42 is substantially cylindrical in extent, being concentric with theaxis of the spindle 28, and having its ends separated for theintroduction thereinto of the fluid-receiving inner end portions 43a and44f=l of hoses 43 and 44, respectively, which are wound about the wall42 and above and below the plate 4I, respectively.

'I'he spindle 28 vis provided with connections 45 and 46 for the supplyof operating fluid through vertical passages 41 and 48 respectively tothe annular channels and 34, respectively. These passages areconveniently drilled from the bottom of the spindle, the bottoms of thesaid passages being closed by means of plugs 41i and 48a.

Short pipe connections and couplings connect the inner ends of the hoses43 and 44 with the channels 34 and 35 respectively. The manner in whichthese connections are made is shown more particularly in Fig, 2 inconnection with the inner end 44 of the hose 44 and wherein a short pipeconnection 44h which extends through the wall of the hub 36 andcommunicates with the annular channel 34 is in turn connected to theinner end 44n of the hose 44 by means of a suitable coupling 44. Themanner of connecting the inner erd 43a of the lower hose `43 to theannular channel 35 is identical with that described for connecting thehose 44 with the channel 34 and hence needs no separate iilustratlon,the short .pipe connection corresponding to 43b being shown at 44h, Fig.3.

49 denotes a short anchoring post carried by the bottom plate 24 of thereel' casing and to which one end of a coil spring 50 is securedl thespring being wound about the lower ends of the spindle 28 and hub 36 andhaving its inner end secured to a post 5I carried by the bottom plate 40of the rotatable portion of the reel.

52 and 53 denote upper and lower journal pins supported by bearings 52ain lip-like extensions 24d and 24e of the bottom and top members of thecasing. Each of these journal pins supports rollers 54 and 55,respectively.

These rollers are provided each with a pair of grooves extendingtherearound, as shown at 55 in the lower roller 55 on Fig. 5, thegrooves on one roller being directly opposed and complementary to thegrooves on the other, whereby they provide roller guides for the hoses43 and 44 extending outwardly with respect to the opening 55b in thewall 24". From these guides, the hoses extend to opposite ends of thecylinder i9.

The plates 39 and 40 of the reel proper are connected and maintained inspaced relation to each other by means of bolts 55 located within thewall 42.

With the parts constructed and arranged as described, it is believedthat the operation will be readily understood. When the main supportingcarriage I4 is elevated, the hoses are unwound from the respectiveportions of the reel by rotation of the latter against the action of thespring 50. Assuming that an object, such as the roll I8, has been pickedup by the forks I6 and that it is desired to tilt the rotatable platformI5, operating fluid will be supplied through the appropriate hose to theappropriate end of the cylinder I9, thereby to impart rotary movement tothe platform I5 and enable the scoop I1 to support the roll I8 in avertical position. When the roll has been elevated to a suiicient heightby the carriage I4 and the truck moved to the place desired for deliveryof the roll, operating duid will be supplied to the opposite end of thecylinder through the appropriate hose, the platform I5 will be rotatedthereby to a, position to enable the roll to be deposited, after whichthe platform I5 may be restored to its load-receiving position and thesupporting platform lowered to such position, the spring 50 winding inboth of the hoses during the descending movement of the carriage I4.

The manner of supplying the operating uid through the supporting spindle28 enables the interior of the hub and the exterior of the spindle to belubricated, where oil is employed as the fluid for operating therotatable carriage.

For convenience of description, the hose reel and its casing have beenassumed to be supported in a position wherein the casing wall 242L isabove the Wall 24 and wherein the plate 39 is above the plate 40, andthe terms top and bottom and upper and lower have been applied to thesame and to other parts of the device and will be applied to the same inthe claims, but without any intention of limiting the posi tions whichthese parts may assume in actual use.

Having thus described my invention, what I claim is:

A lift truck comprising a mobile chassis assembly, vertical mast meansmounted forwardly on said assembly, a carriage slidable on said mastmeans, power means for raising said carriage, said carriage comprising asupport mounted on said mast means and a load carrying member movablymounted on said support, a doubie acting piston and cylinder assemblymounted on said carriage and arranged for moving said load carryingmemberon said support, a reel mounted on said chassis assembly anddisposed behind said mast adjacent a lower portion thereof, conduitguide means disposed forwardly of said reel, said reel and mountingincluding dual-ported xed means cooperating with reel hub means to forma swivel uid joint, a pair of exible conduits, each conduit beingconnected at one end to said hub means, passed about said reel and oversaid guide means, and connected at the other end to one end of saidcarriage mounted cylinder, and means to connect a source of fluid underpressure to said xed ported means.
